对代码的重要建议：您可以使用range()函数而不是制作列表：

with open("CoinMC.txt", 'w') as fp:
    for number, line in enumerate(lines):
        if number not in range(0, 7):
            fp.write(line)

不能使用python保留的input之类的关键字，您在此处使用了这些关键字：

with open("CoinMC.txt", "r") as input:
    with open("CoinMCtemp.txt", "w") as output:
        for line in input:
            if "day" not in line.strip("\n"):
                output.write(line)

回答你的问题：尝试使用以下方法：

str = "Your Data".split("ago")
del str[-1]
str = "ago".join(str)

这将从ago分割字符串并删除最后一项，然后按ago重新加入
